This morning I have observed three SEO posts in the top 15 links on Hacker News:
- Black Hat SEO Case Study: How Mahalo Makes Black Look White
- Some SEO Advice For Bill Gates
- Strategic SEO for Startups
Is this a coincidence, or can it be explained by something else, such as a sudden influx of SEO types to this forum?
I think it is simply tied in to the nature of the web. If you 'inject' a bunch of users via a link on HN in to a spot on the web then from there they will spread like sinking a mineshaft will exhaust the resources in the neighbourhood of the shaft.
Then, when that particular mine is exhausted (no more interesting content to be found around that locus in the web) the subject dies down until someone finds a new and untapped reservoir.
I've seen this happen around all kinds of subjects, from programming languages to hardware hacks and political stuff.
